5 months pregnant, 22yrs, full-time job, lives with strict parents,1st baby, when should I move out or not??

I've live with my parents and I got pregnant! But My parents own the house that we live in, me in the top duplex with my snotty lil sis. They are at the bottom duplex. I never had the chance to actually make choices 4 myself, unlike my friends who moved out at age 18, but no i have a baby I dont want to be embred with filling out a questionaire if I may step out the house,ect. Although, my mom and father doesn't work, and they said they will be babysitters, I wanna move out 2 be a real adult. I understand I wont be receiving much from the father, and moving out or staying at home would have its bitter-sweet consequences, but Im unsure whats best. My plan was to wait 4 my baby to turn 1yrs, but in the meantime...SAVE and pay off credit card bills!!!
